Here’s what people selling books about the end of the world and stuff don’t want you to know. Too much misinformation is going around so that people can cash in!
Pole shift is a rare phenomenon and characterized by the north and the south poles swapping places. Such reversals, recorded in the magnetism of ancient rocks, are unpredictable. They come at irregular intervals averaging about 300,000 years; the last one was 780,000 years ago. There is some sort of hype around pole shift since the fear propaganda has started about the end of the world in 2012 (see my post about 2012).
Pole shift is a process that roughly takes 5,000 years to complete and doesn’t start on a specific date and time and the real truth is that nobody knows when the next one is due. So let’s put an end right now to that 2012 thing before we go any further.
If you came here to know if a pole shift would end our world in 2012, well no.
That being said, to really understand what a pole shift is, we have to take a look at the inner core of our planet. The magnetic field of our planet comes from this inner core, which is mainly a solid ball of iron 70% as wide as the moon and as hot as the sun. It doesn’t spin at the same rate as the earth; it has it’s own rate.What creates the magnetic field is the convection of molten iron, within the outer liquid core and also with the overall planetary rotation. The creation of the magnetic field can be explained with the dynamo effect: When conducting fluid flows across an existing magnetic field, electric currents are induced, which in turn creates another one. When this new field reinforces the original, a dynamo is created which sustains itself. It’s a little more complicated than that and you can do your own research on magnetic fields and dynamo if you want to have more details about it.
There’s a popular belief that wants a pole shift to completely remove the earth’s magnetic field during it’s reversal. It would then expose the earth to space radiation and solar storms. Well, once again, this ain’t true and here’s why from a NASA article:
